Nucleus

The nucleus acts like the brain of the cell. It instructs the cell what to do and when to do it.

Cell wall

The cell wall is made up of cellulose and provides rigid support for the cell. It has specialized pores (openings) to allow materials to enter and exit the cell.

Cell membrane

The cell membrane is a thin covering that hold the organelles inside the cell. It acts like a security guard, only allowing specific materials in/out of the cell.

Ribosomes

Ribosomes are tiny organelles responsible to manufacture proteins (specialized chemicals needed by the cell to survive).

Chloroplasts

Chloroplasts contain chlorophyll, which uses the sun's energy to combine water and carbon dioxide into glucose and oxygen. This process is called photosynthesis.

Cytoplasm

Cytoplasm is a jelly-like substance that fills the cell and cushions organelles. Nutrients move freely through the cytoplasm to the organelles.

Vacuole

Vacuoles are like storage tanks that store nutrients, waste and other substances.

Mitochondria

This organelle is the powerhouse of the cell. They break down glucose and release the stored energy for use by the cell.

Golgi apparatus

The organelle combines proteins made by the endoplasmic reticulum and delivers them to the rest of the cell and also outside the cell.

Endoplasmic reticulum

The ER manufactures proteins for use throughout the cell.

Lysosome

These small organelles contain chemicals that break down food particles and worn-out cell parts.

DNA

Deoxyribonucleic acid. Located in the nucleus of the cell. Contains 4 major chemicals; Thymine, Cytosine, Guanine, and Adenine. DNA determines what you are going to be.

Eukaryotic cells

Make up plants, animals, fungi, and all other life forms, containing numerous compartments or organelles within each cell. Contains a nucleus, Means "true nucleus."

Prokaryotic cells

A group of organisms whose cell lacks a nucleus. All the components, including DNA, mingle freely in the cells interior, a single compartment. Means "before cell."
